EPS (Expanded Polystyrene) pre-expander machine is a device used in
the manufacturing process of expanded polystyrene foam products.
Hopper: The machine has a hopper where the raw polystyrene beads
are loaded. The hopper feeds the beads into the pre-expanding chamber.
Steam injection system: The pre-expander machine is equipped with a
steam injection system that supplies steam into the pre-expanding
chamber.
Agitation system: Inside the pre-expanding chamber, there is an
agitation system that ensures uniform heating and expansion of the
beads.
Exhaust system: The pre-expander machine has an exhaust system to
remove the steam and any volatile gases released during the
expansion process. This system helps maintain a controlled and safe environment within
the machine.
Control panel: The machine features a control panel that allows
operators to monitor and adjust various parameters such as steam
pressure, temperature, and expansion time.
The EPS pre-expander machine is available in different sizes and
capacities to accommodate various production requirements.
The pre-expanded beads produced by the machine are then transferred
to a molding machine, where they are further processed into
specific shapes such as blocks, sheets, or custom-molded products.
Please note that while the description above provides a general
overview of an EPS pre-expander machine, specific machine designs
and features may vary among manufacturers.
